Description

Technical Field

[0001] This invention provides a multi-station polyimide film slitting device, belonging to the field of polyimide film processing technology. Background Technology

[0002] Polyimide films are widely used in the electronics, aerospace, automotive, and optoelectronic industries due to their excellent thermal stability, electrical insulation properties, mechanical strength, and chemical stability. These superior properties make them the preferred material for manufacturing flexible circuits, screen protectors, high-temperature insulation materials, and various high-performance components.

[0003] In some applications, it is often necessary to cut films to fit specific dimensions according to design requirements. Due to the high flexibility and low coefficient of friction of polyimide films, it is necessary to ensure the film is fixed during cutting to guarantee the accuracy of the cutting. Existing polyimide film cutting equipment often changes the fixed state of the film after the film is separated after a single cut, affecting the stability of the film. Therefore, when cutting the film in multiple segments, it is often necessary to adjust the position of the film after each cut, fix the film again, and then cut it again, which is inefficient. To address the above problems, a multi-station polyimide film cutting device is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that when cutting a film into multiple segments, it is often necessary to repeatedly adjust and fix the film, resulting in low cutting efficiency.

[0005] To address the aforementioned problems, this invention proposes the following technical solution: a multi-station polyimide film slitting device, comprising a worktable, a support frame fixedly connected to the worktable, and the film placed on the support frame; a fixed plate located above the worktable is disposed within the support frame, pressing against the film, and the fixed plate has several through slots; an mounting plate is connected upward to the fixed plate via a spring connection structure, and the mounting plate is slidably disposed relative to the fixed plate; several cutters are disposed within the mounting plate; several placement slots are disposed on the upper surface of the mounting plate, and limiting blocks fixedly connected to the cutters are disposed within the placement slots; a hydraulic cylinder is disposed within the support frame, and a pressure plate is fixedly connected to the working end of the hydraulic cylinder; the pressure plate presses against the mounting plate, and the pressure plate is fixedly connected to the mounting plate.

[0006] As an improvement, the spring connection structure includes a fixed rod and a pressure spring; the fixed rod is fixedly connected to the fixed plate, and the mounting plate is slidably sleeved on the fixed rod; the pressure spring is located between the mounting plate and the fixed plate, and the pressure spring is sleeved on the fixed rod.

[0007] As an improvement, a limiting plate is provided above the mounting plate, and the limiting plate is fixedly connected to the fixing rod.

[0008] As an improvement, the pressure plate closes all the placement slots on the mounting plate, and the pressure plate is fixedly connected to the mounting plate by screws.

[0009] As an improvement, the number and position of the through slots correspond to the number and position of the cutters.

[0010] As an improvement, the worktable is provided with several grooves, the film is pressed on the grooves, and the number and position of the grooves correspond to the number and position of the through slots.

[0011] The beneficial effects of this utility model are:

[0012] 1. The fixing plate has several through slots. The fixing plate presses on the film, and the fixing plate is connected to the mounting plate upward through a spring connection structure. The mounting plate is equipped with several cutters. The fixing plate and the mounting plate are connected, and through slots are opened on the fixing rod. During cutting, the fixing plate is used to fix the entire film, and then the sliding of the mounting plate drives the cutters to cut the film through the through slots. This can realize multi-station cutting, eliminate the need to repeatedly fix and adjust the film, and improve the efficiency of multi-segment cutting.

[0013] 2. The pressure plate presses on the mounting plate, which can limit and fix all the cutters. Releasing the pressure plate will simultaneously release the cutters from their fixation. Conversely, fixing the pressure plate to the mounting plate will simultaneously fix all the cutters, making it convenient to adjust and replace the cutters.

[0014] 3. A pressure plate is fixedly connected to the working end of the hydraulic cylinder. Through one hydraulic cylinder, the mounting plate and the fixed plate can be moved downward at the same time. The fixed plate is located below the mounting plate, which can quickly and sequentially complete the fixing and cutting of the film, resulting in high cutting efficiency. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figure 1-4 As shown: This utility model provides a multi-station polyimide film slitting device, including a worktable 1, a support frame 2 fixedly connected to the worktable 1, and a film 10 placed on the support frame; a fixed plate 7 located above the worktable 1 is provided in the support frame 2, the fixed plate 7 presses on the film 10, and a plurality of through slots 8 are opened on the fixed plate 7; a mounting plate 6 is connected upward to the fixed plate 7 through a spring connection structure, and the mounting plate 6 is slidably arranged relative to the fixed plate 7; a plurality of cutters 9 are provided in the mounting plate 6; a plurality of placement slots 12 are opened on the upper surface of the mounting plate 6, and a limiting block 11 fixedly connected to the cutter 9 is provided in the placement slot 12; a hydraulic cylinder 3 is provided in the support frame 2, and a pressure plate 4 is fixedly connected to the working end of the hydraulic cylinder 3; the pressure plate 4 presses on the mounting plate 6, and the pressure plate 4 is fixedly connected to the mounting plate 6.

[0022] By setting a fixing plate 7 connected to the mounting plate 6, the film 10 can be fixed and cut quickly and sequentially. Multiple through slots 8 are opened on the fixing plate 7, which can perform multi-station cutting and improve cutting efficiency. It also facilitates the replacement of the cutter 9 and the adjustment of the spacing between the cutters 9.

[0023] like Figure 3 As shown, the spring connection structure includes a fixed rod 15 and a pressure spring 14. The fixed rod 15 is fixedly connected to the fixed plate 7, and the mounting plate 6 is slidably sleeved on the fixed rod 15. The pressure spring 14 is located between the mounting plate 6 and the fixed plate 7, and is sleeved on the fixed rod 15. When the pressure spring 14 is compressed, it can generate a rebound force on the fixed plate 7, thereby causing the fixed plate 7 to exert pressure on the diaphragm 10. A limiting plate 13 is provided above the mounting plate 6, and the limiting plate 13 is fixedly connected to the fixed rod 15. The setting of the limiting plate 13 can prevent the mounting plate 6 from detaching from the fixed rod 15.

[0024] like Figure 3 , 4As shown, the pressure plate 4 closes all the placement slots 12 on the mounting plate 6, and the pressure plate 4 and the mounting plate 6 are fixedly connected by screws 5, facilitating the disassembly of the pressure plate 4 and the mounting plate 6. The number and position of the through slots 8 correspond to the number and position of the cutters 9. Several grooves 16 are provided on the worktable 1, and the film 10 is pressed on the grooves 16, and the number and position of the grooves 16 correspond to the number and position of the through slots 8; the grooves 16 provide space for the movement of the cutters 9, preventing the cutters 9 from directly cutting onto the worktable 1.

[0025] The principle of this utility model

[0026] Before cutting the polyimide film 10, the hydraulic cylinder 3 is activated. Driven by the hydraulic cylinder 3, the mounting plate 6 and the fixing plate 7 move upwards away from the worktable 1, ensuring sufficient space for the film 10. The film 10 is then placed on the worktable 1. The hydraulic cylinder 3 is activated again. Driven by the pressure plate 4, the mounting plate 6 and the fixing plate 7 move downwards until the fixing plate 7 is in contact with the film 10. Figure 1-2 As shown.

[0027] When the fixing plate 7 is in contact with the film 10, the hydraulic cylinder 3 continues to operate. Due to the constraint of the worktable 1, the fixing plate 7 presses against the film 10 and no longer moves, while the mounting plate 6 can still drive the cutter 9 to move downwards. At the same time, the mounting plate 6 slides relative to the fixing rod 15, and the mounting plate 6 compresses the pressure spring 14. The compression of the pressure spring 14 generates a rebound force on the fixing plate 7, causing the fixing plate 7 to exert a pressing force on the film 10, thereby increasing the tightness of the fixing plate 7 on the film 10. As the mounting plate 6 continues to move downwards, multiple cutters 9 simultaneously pass through the through slots 8 on the fixing plate 7 to cut the film 10, achieving a multi-station cutting effect with high cutting efficiency.

[0028] When it is necessary to replace the cutter 9, or to change the number of cutters 9 to alter the slitting spacing of the film 10, simply unscrew the screw 5 to release the fixation between the pressure plate 4 and the mounting plate 6. Activate the hydraulic cylinder 3 to raise the pressure plate 4, quickly releasing the fixation on all cutters 9. Simply pull the cutter 9 from the mounting plate 6 from bottom to top, and place the new cutter 9 from top to bottom into the mounting plate 6, ensuring the limiting block 11 is positioned within the placement slot 12. This completes the cutter 9 replacement. Simultaneously, the slitting spacing can be adjusted by reducing the number of cutters 9 to increase the spacing between adjacent cutters 9. After adjusting the cutters 9, re-fix the pressure plate 4 and mounting plate 6 using the screw 5. The fixed connection between the pressure plate 4 and mounting plate 6 seals all placement slots 12, thus securing all cutters 9 and ensuring high operational efficiency.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
